A method and apparatus for filtering and/or sorting responses to electronic requests for quotes for a product or products offered for sale includes comparing first data of each of a plurality electronic quotes to first data of an electronic request for quote. Each of the plurality of electronic quotes is classified as either a matching quote or a non-matching quote. After the quotes are classified, each classified quote is ranked, for example, by the total price of the product or products offered for sale.

Inexact matches can be adjusted to allow comparison between exact matching quotes and the adjusted inexact matching quotes.
